Ophthalmology & Visual Sciences in China Today

Xie Lixin

Strategic Study of CAE 2003, Volume 5, Issue 1, Pages 1-5

Abstract:

Since the reform and opening-up, ophthalmic resources have rapidly developed in China. On the basis of latest data, this article mainly introduces the present clinical and experimental studies in China on common blinding eye diseases of cataract, cornea, refractive error, vitreous & retina and glaucoma. Great progress has been made in clinical diagnosis and treatment with state-of-the-art ophthalmic equipment and internationally renowned experts in part of cities. However, the difference in overall ophthalmic level between China and developed countries is still pronounced. Main facilities are totally dependent upon importation from abroad. Experimental eye research is facing challenges as well. It requires more policy and financial supports to realize great breakthrough in this frontier.

Abstract: In this paper, a supervisory computer network for Borneo-Wide Power Grid system have been proposed and implemented, which includes a renewable power generation and advanced metering infrastructure. An Internet-based communication network running on multiprotocol label switching (MPLS) has been implemented for a smart power grid, with the addition of the renewable energy monitoring system. The centralized supervisory control and data acquisition systems (SCADA) are replaced by a wide area monitoring system(WAMS) comprising of a phasor measurement unit (PMU). The implemented communication network used advanced metering infrastructure that operates on worldwide interoperability for microwave access (WiMAX), wireless fidelity (Wi-Fi) and low power Wi-Fi, which are proposed for the distribution systems of Sarawak Energy. The proposed wide area network (WAN) is simulated using OPNET Modeler and the results are compared with the existing WAN used by Sarawak Energy.

Advance in FCC Process Reaction Chemistry

Xu Youhao and Wang Xieqing

Strategic Study of CAE 2007, Volume 9, Issue 8, Pages 6-14

Abstract:

Faced the stringent challenge of FCC process, the multi-dimensional reaction structure was proposed for FCC process reaction chemistry. The multi-dimension reaction structure mode was established on the basis of hydrocarbon reaction chemistry over acid catalyst, but the former was different from the latter. FCC process with multi-dimensional reaction structure has more production modes. The multi-dimensional reaction structure was used to successfully develop MIP process aiming at maximizing iso-paraffins in cracked naphtha and MIP-CGP process aiming at cleaner gasoline and more propylene.

Advanced Bioprocess Development and Manufacturing Technologies in High-Throughput Miniature Bioreactors

Jiao Peng, Chen Biqiang

Strategic Study of CAE 2016, Volume 18, Issue 4, Pages 44-50 doi: 10.15302/J-SSCAE-2016.04.007

Abstract:

In recent years, the importance of rapid response time to virulent infectious disease is widely recognized. However, the traditional technologies for bioprocess development and manufacturing will not succeed in winning this war. US healthcare companies and related organizations including US Department of Human Health and Service, proposed and started working on the next generation of technology platforms for advanced bioprocess development and manufacturing (ABDM).The development of ABDM is to significantly reduce the timeframe for bioprocess development and manufacturing, making it possible to promptly respond to outburst of pandemic influenza and prevent it from outspreading. Meanwhile, the development of precision medicine also presents new demands to the biopharmaceutical industry. With the demand of small-scale production and fast turn-around time of precision medicine, the duration of development and manufacturing needs to be accelerated significantly. At the same time, the number of sub-groups of the product would increase, and the batch sizes and amount of final product would decrease, as well. To satisfy the demands of small-scale production and fast turnaround time of ABDM, micro- and mini-bioreactor is the key equipment. The major technologies of ABDM include high throughput screening and process development based on micro- and mini-bioreactors, disposable technology, modular unit operations and flexible manufacturing. The development of ABDM will directly strengthen the National Security, improve the welfare of the people, and it also provides great social and economic values. The impact of this platform will radiate to the entire biomanufacture industry, and open a whole new era for the bioprocess development and bio-manufacturing.

LIU Lin, YU Xiaoli

Frontiers in Energy 2008, Volume 2, Issue 1, Pages 14-19 doi: 10.1007/s11708-008-0004-7

Abstract: To investigate the feasibility and outlook of air-powered vehicles including compressed air-powered vehicle and liquid nitrogen-powered vehicle, thermodynamic analysis and experiment data were used to analyze the energy density, performance, safety, running efficiency, fuel circulation economy and consumer acceptance, etc. The results show that compressed air and liquid nitrogen have similar energy density as Ni-H battery; the characteristics of an air-powered engine is suitable for driving a vehicle; the circulation efficiency of liquid nitrogen is 3.6%–14% and that of compressed air is 25%–32.3% in practice, and existing technology can assure its safety. It is concluded that though the performance of an air-powered engine is inferior to that of the traditional inert combustion engine, an air-powered vehicle is fit for future green cars to realize the sustainable development of society and environment.

A feasibility study of the measuring accuracy and capability of wireless sensor networks in tunnel monitoring

Xiaojun LI, Zhong JI, Hehua ZHU, Chen GU

Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 2, Pages 111-120 doi: 10.1007/s11709-012-0150-1

Abstract: Fire disasters and the deterioration of tunnel structures are major concerns for tunnel operation and maintenance. Traditional wired monitoring systems have many drawbacks in terms of installation time, overall cost, and flexibility in tunnel environments. In recent years, there has been growing interest in the use of wireless sensor networks (WSNs) for the monitoring of various structural monitoring applications. This paper evaluated the feasibility of applying a WSN in the monitoring of tunnels. The monitoring requirements of tunnels under explosion and combustion fire scenarios are analyzed using numerical simulation, and the maximum possible distance for temperature sensors is derived. The displacement monitoring of tunnels using an inclinometer is investigated. It is recommended that the inclinometer should be installed in the 1/4 span of the tunnel structure. The maximum wireless transmission distances in both outdoor and tunnel environments were examined. The influences of surface materials and sensor node locations on the data transmission distance in tunnel environments were also investigated. The experimental results show that the data loss in tunnel environments is approximately three times that in outdoor environments. Surface material has a considerable influence on the transmission distance of radio signals. The distance is 25 ? 28 m for a raw concrete surface, 20 m for a brick surface, and 36 m for a terrazzo surface. The transmission distances along the middle of quarter points are approximately 0.9 ( is the transmission distance in the center of the tunnel), and the relative error is less than±3%. The transmission distances at different locations along the bottom exhibit significant differences, decreasing from the middle to the corner point, with distances of approximately 0.8 at the quarter points and minimum distances of approximately 0.55 at the corner points.
